7, 14, 28, 35, 70, ?
77
The operations on the terms alternate between ×2 and +7.
Check: \(7 \times 2 = 14\), then \(14 + 7 = 21\)... here the series uses the pattern \(7 \times 2 = 14\), \(14 \times 2 = 28\), \(28 + 7 = 35\), \(35 \times 2 = 70\).
So the operations run as ×2, ×2, +7, ×2, and the next step is +7: \(70 + 7 = 77\).
Hence, the missing number is 77.
